Abstract
The present disclosure relates to air assemblies having an inflation, a deflation, and a closed state for use with inflatable products, such as air mattresses. Specifically, the present disclosure relates to air assemblies where the configuration of the air assembly can be changed manually by a user by operating a directional control valve to inflate, deflate, or close the inflatable product. The directional control valve may also activate a pump in the inflation and deflation states and deactivate the pump in the closed state.
